Bend your fingers and control your lights. Goes from 0° to 180° (larger flex angle possible). Shorther version available as BendMicro, longer version as BendShort. See this videoclip for a demo of the BendShort !
Application examples
- Combine with the TouchGlove and create your own custom dataglove for capturing finger bending, capture hand movements with a GForce3D-3.
- Go whole-body with a bodysuit, capture all your joints' movements and express with all your extremities. A couple of Curls will capture muscle tension. Use a GForce3D-3 on your feet and hands to capture kicks and punches. A Hot will keep you in check of your body temp.
- Since it's such a thin and flexible sensor, it's usable for measuring airflow.
- Put it bent across an elastic band so that when you stretch the band you can measure the tension in the elastic band.
- Wireless Wi-microDig with one of our BatteryPacks recommended in all cases to operate without tether.
- For bookworms: has also been used to detect turning of pages.
Technical specifications
Product BendMini sensor Version 1.1 (November 2005) Sensing parameter flex angle multiplied by flex radius Sensing method piezo-resistive Range 0° to 180° (larger flex angle possible) Minimum flex radius 5 mm (0.2 inch) Output impedance 6 KOhm (at 0° flex angle) to 500 KOhm (at 180° flex angle), in parallel with 47 KOhm Calibration (using minimum flex radius) Degrees Voltage (use 5 V power supply) 7-bit MIDI value (use 'no processing' editor preset) 0 4.33 110 180 0.00 0 Power supply 1.0 to 10 V DC, 0.1 mA at 5 V Sensor dimensions 63 x 7 x 0.1 mm (2.5 x 0.3 x 0.004 inch) Weight 15 g (0.5 oz), incl. cable Cable 0.90 m (35 inch) twisted, unshielded, red wire = power, black wire = ground, white wire = sensor output, maximum extension 30 m (98 ft) Connector male plug with a row of 3 pins spaced 2.54 mm (0.100 inch) Application notes The sensor output is determined by both the angle between the ends of the sensor as well as the flex radius; bending the sensor sharply will result in a higher value than bending the sensor smoothly, when keeping the ends in the same position. Shorther version available as BendMicro, longer version as BendShort.
